Patent DE-2652514-A1 (DE)
Title: Electronic changeover switch system - is manually or remotely operated with two PIN diodes connected in series, with their junction point connected to changeover switch
Inventor: UNGER JOHANN GUENTHER ING
IPC: H04B1/18
Filed: 1976-11-18
Abstract: The switch is intended for two separate aerial down leads or HF signal sources, for connection to the aerial input socket of a TV receiver. Two PIN diodes are connected in a series, so that each signal input socket is connected through an isolating capacitor to the anode of one diode and cathode of the other. The junction point between the diodes is directly connected to the HF input socket of the receiver. a further connection is made through an inductance to a change-over contact of a mechanical or electronic switch, to whose make and break contacts a DC voltage of opposite polarities is applied.

Title: Torque booster for car - has turbine blades on wheels and transmission shaft driven by air ducted from slip stream or radiator blower
Inventor: KOEPPLE GOTTHOLD
IPC: B60K16/00
Filed: 1976-12-14
Abstract: The inside edges of the car wheels are fitted with turbine blades which are drived by ducted air from a duct under the car.

Inventor: BINGER PAUL DIPL CHEM DR
IPC: C07C13/61
Filed: 1977-02-24
Abstract: In a new process for the prodn. of methyl-cyclopentanes substd. by catalytic codimerisation of methylene-cyclopropane with olefins, the codimerisation is carried out in the presence of Pd(O) cpds. as catalysts.

Title: Photometric blood corpuscle aggregation rate measurement - uses disc -shaped cuvette with rotating side walls to reduce sedimentation
Inventor: EHRLY ALBRECHT PROF DR MED
IPC: G01N15/05
Filed: 1977-02-24
Abstract: A method is used for measuring and recording the aggregation rate of particles suspended in fluid esp. of red blood. It is designed to eliminate sedimentation of the blood and the associated errors. It ensures optimum aggregation conditions and a corresponding high success rate, without leading to sedimentation and separation, short measurement time and minimal sample quantity. Light is passed through the sample which is in a disc-shaped curvette whose sidewalls rotate about a horizontal axis. During the measurement the sample undergoes shear forces at the curvette side walls and is maintained at constant temp. A photometer receives the transmitted light.

Title: Two colour, seven segment LED display - uses optical segments with two differently coloured elements to avoid confusion between time and date displays
Inventor: KIELWEIN FRITZ
IPC: G09F9/33
Filed: 1977-03-31
Abstract: A seven segment display of numerical information is based upon segments that may be activated in one of two colours e.g. red or green.

Title: Sack bundle assembly machine - has stacking tables with counter supplying bundling mechanism via conveyors
Inventor: HATCH RONALD FRANK
IPC: B65B35/50
Filed: 1977-05-12
Abstract: The machine stacks and assembles into bundles lengths of hose material for forming into sacks. A series of stacking tables (19-22) receive a succession of hose lengths so as to form them into stacks. A mechanism counts up and predetermined number of lengths delivered to each table, and a further mechanism forms bundles from the stacks (50) placed one on top of the other. Conveyors (38, 40) transport a succession of stacks, each containing a predetermined number of lengths, from the stacking tables to the bundle-forming mechanism. Each table can have a support, movable between a first position above it and a second one close to the first. The lengths are individually delivered to the support, which is pulled away rapidly from underneath them, so as to drop them on the table.

Title: Perforated tape reader with enhanced security - uses modulated reflected scanning beam and reference comparison
Inventor: LITOVTSCHENKO SERGEJ SERGEEVIT
IPC: G06K7/10
Filed: 1977-08-01
Abstract: The perforated tape reader consists of a light source whose beams pass through the perforations and at the same time are partially absorbed and reflected by the material of the tape. The beams emerging on the lower side of the perforations are modulated further and fall onto a reflector. From here they are reflected back through the modulation unit and pass again through the same perforations. The beams strike the photo-cells of transducers. The signals from the photo-electric sensors pass to comparators after having been amplified. The synchronisation inputs of the comparator are fed with a standard signal derived from a reference source.

Title: Controlled-duration continuous-wave HF ignition system - has engine-timed unit for controlling electronic switch which starts and stops oscillator containing transformer
Inventor: CANUP ROBERT EUGENE
IPC: F02P3/01
Filed: 1978-03-15
Abstract: The controlled-duration continuous-wave HF ignition system for IC engines has an output transformer with a control winding. The system has an oscillator with the output transformer included inside. The oscillator generates spark energy, and an engine-timed unit controls an electronic switch that starts and stops the oscillators by breaking and making a loading circuit for the control winding. The arrangement is such that the engine-timed unit controls the beginning of all spark intervals, and the end of each spark interval at less than a predetermined speed of the engine. But only time constant element controls the end of each spark interval at more than the predetermined speed of the engine.

Patent DE-2813475-A1 (DE)
Inventor: SAALASTI TAPIO
IPC: B61C9/34
Filed: 1978-03-29
Abstract: On the drive shaft (2) of the motor (1) there is a hydraulic torque transducer (14) with a primary (P) and a secondary pump blade wheel (TU). The secondary shaft (3) bears at the end a bevel gear wheel (4) which is simultaneously in engagement with the two ring gear wheels (5, 6). The hub sleeves (5', 6') of the ring gear wheels are seated on the transversely located transmission axle (7) which has at each end a clutch (5', 9 and 6', 10). Depending on the desired direction of travel, forwards (E) or backwards (T), the transmission axle is coupled by means of these couplings to one or other ring gear wheel (5 or 6) rotating in the opposite direction. The drive is provided from the gear wheel (8) which is seated fixedly on the transmission axle (7) via the step-down gearing (11, 11') to the drive shaft (12) of the mobile machine (for example a diesel locomotive). The force transmission device permits jolt-free starting up and switching over at any time into any direction of travel even whilst the machine is moving. When switching over during travel, the device automatically triggers the braking process until the machine comes to a standstill and automatically triggers the starting up in the opposite direction. <IMAGE>

Title: Worm for driving rotary valve spindle - has sliding fit on shaft to allow disengagement if overload torque is applied
Inventor: STRATIENKO ANDREW
IPC: F16D21/06
Filed: 1978-04-04
Abstract: The valve spindle carries a worm wheel that is in mesh with a worm on the operating shaft (36). One end of the operating shaft is connected to the primary drive which is an electric motor. The opposite end of the operating shaft is linked to a hand wheel (72) which forms the manually operated secondary drive. Each operating shaft connection is provided with a detachable coupling, and an interlocking device (26) ensures that only one of the two couplings is engaged at any time. If the torque applied to the valve spindle is above an allowable value, the worm is able to slide along the operating shaft and disengage the worm gear.
